BA/MA : Ejecta distribution experimental studies for shallow oblique impact event. (Contact: Yanwei Li) The mass, speed and angular distribution of ejecta varies with impact incident angle and speed. The students will carry out lab experimental tests use the multi-anode set up and/or delay line detectors using the 20 kV dust accelerator.

BA/MA : Ions distribution simulation for multi-electrode and MCP multi-anode detector by SIMOIN software (Contact: Yanwei Li) The multi-electrodes and MCP multi-anode detector are the key monitoring system for ejecta distribution experiments. The signals recorded by electrodes depend on the their shapes and E-field potentials. The student will simulate the electron trajectory and calculate the total charge of each electrode using SIMOIN software.

BA/MA : Lunar dust cloud dynamic model (Contact: Yanwei Li) The lunar dust could model was detected by LDEX detector, and the densify of the dust particle in the cloud varies with annual meteoroid showers. The student needs set up a primary dynamic model of the dust cloud related with lunar gravity field, meteoroid shows model (IMEX) and impact ejecta distributions.

BA/MA : Electrical design for the 3.5 MV dust accelerator facility. The mechanical design of a 3.5 MV dust accelerator has been completed. The student needs to design an electrical program for the dust accelerator facility, including power connection to pumps, valves, power supplies…... The softwares could be Catia, Autocad,…. (contact: Y. Li, R. Srama)

BA/MA : The design of a vacuum control system interface for beam line and test chamber of the 3.5 MV Dust Accelerator Facility The mechanical design of a 3.5 MV dust accelerator has completed. The student needs to design a vacuum control system interface for the beam-line and test chamber of the dust accelerator facility, including pumps, valves, gauges….. The softwares could be Labview, Matlab,….(contact: Y. Li, R. Srama)

BA : Control interface for a vacuum articulation platform A 3.5 MV dust accelerator will use an experiment test chamber with a new articulation platform. The platform has 3 degrees of freedom and a computer interface shall control the stepper motors and shall monitor the current experiment position in real-time. The control system might be based on Matlab/Arduino/RaspberryPI or similar. (Contact : Yanwei Li, Ralf Srama)

BA/MA : The Dust trajectory sensor for the Destiny Dust Analyzer The japanese mission Destiny Plus will launch in 2022 for an interplanetary trajectory with a Phaethon flyby in 2025. The mission will carry a dust telescope for the measurement of interstellar and interplanetary dust particles. The dust telescope contains a time-of-flight mass spectrometer and a trajectory sensor based on charge induction. The system contains two planes of grid electrodes. This thesis will design, manufacture and test the trajectory sensor subsystem. The tests will be performed at a dust accelerator.(contact: Y. Li, R. Srama)
